Very nice, but sizing is inconsistent
Size: 10 Wide, Color: Ivory/White/British Tan
All of these Cole Haan shoes are extremely well made and I like the styling. On the other hand, the sizing is very inconsistent and you may end up having to do a lot of returns trying to find the right size. Then if you get a different color of it, you may find the sizing different yet again. If you find your right zie, they are really nice shoes at a very reasonable price for the quality.

I love this brand. These shoes look and fit great!
Size: 13 Wide, Color: Black/White/Black
I love wearing Cole Haan shoes. This is the second pair I’ve owned and the style just gets me. I’ve worn these to work at a great professional job every day, not just casual Friday. I wear these when I head out shopping or to dinner. They are functional, comfortable, built for regular and bigger wider feet and comfortable. I am 6 feet tall and my feet have changed size over the years to me needing a wider shoe to relieve pressure on my toes and front wide porting of my foot. So the 13W feels great and still walks the same as a regular 14 but more comfort for me. They look amazing and qualify in some offices as dress shoes (depending on company rules they will justify a sneaker as a shoe with the tan colored “gum” sole as a sneaker) so check company policy. The black sole on this makes it look more dressy. I am switching out the laces to match my previous Cole Haan because I think the white shoelaces look better. As an adult, aside from my Kenneth Cole boots Reaction boots and Doc Marten’s these are the only shoes I will pay 3 digits for. This looks like skater shoes but with a more mature look.

I am certainly glad I found them and finally ordered
Size: 10, Color: Ivory/White/British Tan
A bit bulkier than my Stan Smiths Leather versions, but actually more comfortable. They seem to be a bit "clunkier" looking than a streamline Stan Smith, but it's a matter of style. It works for a change of pace. Gets or picks up dirt a bit, but cleans well, except the canvas part. Has lasted almost 6-8 months with very little signs of wear. Feels very secure in any type of weather or condition. Great alternative or addition to having a pair of Stan Smiths.

Love the look, but Narrow
Size: 10, Color: Marine Blue/Woodbury/Ivory
What is for my son-in-law, he loves them, but had to switch them out twice because they run very narrow. He doesn’t have a wide foot at all so be careful when you purchase. Other than that they are a good looking shoe and he really likes them.
